Thanks Adam, Nice feature that makes a conversion like this simple

Ok Thanks Adam so 1 T/tdc gives me the 8 ign events/720 deg, base timing set by distributor position ? Thanks for the MSD box tip Not even sure what cam is in it , if it looks like Vac signal will be weak i will just start with TPS

Hi all Been asked to help with an efi conversion on an old W model chev They have an Atom , setup with TPS and MAP, and i am going to add Lambda Replica 6x97 carbs with internal Edelbrock 29lb injectors , one / carb , Optical distributor still with 8 pole chopper wired direct (i am assuming) to trigger 1 Single coil, only remembered i should have checked if it was a smart coil after leaving Was going to setup as traditional fuel tables as i am more familiar with that and i dont see future changes once setup and running I am still to test the pinout so i can be sure how it has been wired , esp for trigger and injector options in setup any comments about best way to use this all are most welcome chopper, remove 1 for missing tooth or 7 for single trigger or find another trigger mechanism ? Hints on starter mapping ? was going to look at just beginning with the Atom sample , making setup changes and playing with master fuel numbers until i get it running

Actually just remembered the gen 1 busa has 2 crank trigger options, 99-2000 was 8 pole evenly spaced, 2001 onward was 24-1 and then gen 2 had 24-2 if your not sure which you have it will need an inspection Also if you have not done so already, the crank trigger wiring shares a harness with the alternator, depin these and separate from that harness for a cleaner signal.

my Busa is 255, but gen2 and the cam pin position is a couple of degrees different on them and my cam timing is not std gen1 setup is in the help file

+1 on the merge angle Had a bike come here with same problem, it would actually make 10 psi with the wastegate removed , dragging air into the turbo rather than letting exhaust out If you dont want to replace the housing i would cut the pipe off the housing and remake in same position with an angle cut outlet to compliment flow

Try removing a couple of degrees timing at cranking rpm

Are plugs in cranking trying to fire or is that turned off ? If we have had problems like that on the Suzukis and Kawasaki, they were so small not to notice Upgrade cable size ??

Is the Dash configured for link ?

Yes 4 bikes running these with either Link or Vipec

Looks like the same hall effect sensor we have on the later gsxr Suzuki's

We use the link on turbo bikes, dual injectors , big cams , low compression , ITB, Using MAP/BAP X over base setting with TPS/rpm fuel table , staged secondary injectors and MAP based secondary staging table would this do what your wanting ?

I would add an extra condition so you dont bump the shift at the wrong time (like key on not running) and bend the shift fork , something like rpm or speed related

Done Thanks Brad

Northern Victoria Aussie I dont mind shipping if you dont , it will fit in a small flat rate box
